Figure 5 is a similar section taken on the line of Figure 2, looking in the opposite direction, and

Figure 6 is a tra sversc section tl'lrough the complementary curved plates that "coin stitute the arm support.

In the drawings, wherein for the purpose of illustration is shown the preferred "embodiment of my invention, the nunleral 1 designates generally the arm support of my improved surgical appliance, the same including a pair oi elongated plate like incur bore 2 and 3 respectively. Each of the plates tapers gradually from one end to the other and furthermore, each plate is curved transyersely throughout its entire length. The inner edge portions of these plates are adepted for disposition in overlapping relation as shown very clearly in Figures 5 and 6 of the drawings. A pair of spaced clips are secured on the under side of the inner edge portion of the plate 3, and the free ends of these clips are spaced with respect to the bottom edge portion of this plate 3, for receiving the inner edge portion of the co1nplementary transversely curved plate 2, as shown Very clearly in Figure 6.

These plates are adjustably secured together, so that said arm rest or support may be made Wider or narrower, depending upon the size of the arm of the patient on which the appliance is to be attached, and the attaching means including a pair of apertured.

lugs 5 depending from the side of the plate adjacent the respective ends thereof, and the apertures of these lugs are threaded. Formed on the bottom face of the plate 3, are the pairs of spaced apertured lugs 6 and 7 respectively, that depend downwardly, each pair of aperlru'ed lugs associated With the plate 3 being disposed in alignment With the respective apertured lugs that depend from the plate 2, as clearly indicated in Figure 3 oil the drawings. a

A. collar 8 is adapted for disposition between each pair of apertured lugs 7 and ex tending through these apertured lugs and the collar is an elongated bolt 5, the inner threaded end thereof being threaded through the threaded aperture of the adjacent lug 5 that depends from the bottom of the plate 2. A

thumb engaging member is formed on the outer end of each bolt to facilitate manual actuation-thereof. A pin or the like, shown at 11, extends radially through the collar for engagement with the respective bolt, so that when the thumb engaging portion 10 is turned, the threaded end of the bolt will eooperate with the threaded lug to effect a sliding movement of the plate members in opposite directions. This construction provides a means for adjusting the plates away from or toward each other as is obvious from the construction shownv in Figure 3.

.The outer edges of the plates 2 and 3 are rolled, and a rod 12 extends through the i rolled outer edge of the plate 3, and an additional rod 13 extends longitudinally in the V ends'of the arm support or rest 1.

rolled outer edge of the plate 2. As is shown more clearly in Figure 1, theintermediate portion of the outer edge of the plate 3 is cut away so that the'intermediate portion of the rod '12 is exposed and hingedly secured at one end on this rod 12 are the sheet metal for positively clamping theappliance on the arm of the patient. The intermediate or crown portion of each strap member is slight- 1y bent inwardly to form an arched rest piece 17-, for apurpose to be presently described.

' Forming a salientpart of the present in- I ventionisthe tourniquet member, designated generally by the number, 18. This member comprises aseg'ment-al band, comprising the upper and lower semi-circular sections 19 and 20respectively. These sections are secured together at one end by a hinge connection, shown at 21','thefree ends of the sections being detachably-secured together by a suitable fastening means that comprises a pin 22 projecting outwardly from the outer side of the lowersection 20, a spring strip 23 being 'fixedlyseeured at its upper end at the outer face of the adjacent section 19, and the lower end of this spring strip extends downwardly for disposition over the outer face of the ad jacent portion of the lower section 20 and this portion or the strip is formed with an opening to receive the pin 22, as shown very clearly in Figures 2 and 4 of the drawings.

A pair of retractile coil springs 24 extend across the hinged ends of the sections, the lower ends of the springs being secured to the lower sections, while the upper ends of these springs are connected to the upper sections and manifestly, when the sections are secured together at their tree ends, the springs are placed under tension. The manner in which these springs cooperate to force the segmental tourniquet band to an open position will hereinafter be more fully described.

This tourniquet member is supported, at the rear end of the arm rest or support 1, and the lower section 20 is formed in its inner edge with the elongated groove or slot 2:), to ac commodate the rear edges of the plates 2 and 3, as well as the rear ends of the rods 12 and 13 respectively so that the tourniquet member will be properly supported on the rear end of the arm rest. In Figures 3 and 4., the lower section is shown as consisting of a pair of segments which are formed at their adjacent ends with a tongue and slot, and a plate 2! extends over this tongue and slot arrangement, the plate being secured to the under side of one of the segments.

A padded arcuate shaped constrictor head 27 is supported in the segmental tourniquet member for vertical adjushnent, and an adjusting screw 28 is threaded through an opening provided therefor in the top of the upper section 19, the lower end of this thumb screw being swivclly connected to the head 27 as indicated in Figure 4. 4

To prevent rotation of the constrictor heads 2?, I provide the upwardly diverging arm 29 that are connected at their lower ends to [be upper-face of the head 27, adjacent the respective ends thereof, and. the upper ends of these arms project through the clongat ed slot s 30 formed in the upper section 19 on opposite sides of the thumb screw 28, as also shown very clearly in Figure 4.

Vhen the thumb screw 28 is turned in one direction, the head 27 moves down 'ardly to effect a congested condition of the blood vessel at a point above where the intravenous injection is to be made.

Also forming an important part of the present invention is the latch plate lrippin; means, and the same includes an elongated rod 31, that extends through suitable bearing portions 32, formed at the outer edge of the plate 3, at the ends thereof. This rod extends along the outer sides of the free end portions of the clamping straps 14 and 15. A thumb engagin member 33 is arranged on the forward end of this rod to facilitate turning thereof.

The rear end of the elongated rod 31. projects through a bearing 34, arrangedv on the outer face oi. the lower section 20, adj aeen t the free end thereof, am. clearly rlnvw in Figure 2, the rear end of the rod is formed with a. laterally disposed finger 35, that is disposed underneath the free end portion of the latch plate 23.

\Vhen the parts are arranged as shown in Figures 1 and 2 of the drawings, the surgical appliance is in position for use, so that an intravenous injection may be made into the lll till

veins. The cradle 17 formed in the top portion of the hand will provide a rest tor the hypodermic syringe, during the ad1ninistrati on or injection oi the serum, into the veins, and the arm support will tend to steady the arm at the patient and also the hand oi the operator will be steadied.

litter the intravenous injection operation. has been completed, the operator turns the thumb enp'agin portion 33 in one direction, so that the i ger 6:35 will force the free end o t the swing plate 23, outwardly, out of engagement with the pin 22, and the retractile coil sprin 2a will swing the upper section 19 ot the tourniquet nien'ibcr upwardly, thus opening this member. The free ends ot the arm encircling hand may then be disengagediroin the outer edge of the plate 2 to facilitate the removal of the appliance from the arm of the patient,

lit will thus be seen from the foregoing description that l have provided a surgical appli ance that is used to r intravenous eetions, and by reason of its simplicity, the a 'npliance can be readily and easily adjusted, in order to properly attach the same on the arm of the patient. Furthermore, an appliance oi? the above mentioned character will be positive and eiiicient in carrying out the purpose i'or which it is designed.
